“…By far, the measures pursued to reduce the economic and environmental disadvantages of UHPC are limited in most cases to the application of industrial by-products or waste materials without sacrificing the UHPC performance [7,8,[12][13][14][15]. Nevertheless, in most cases in the literature, for the mix design of UHPC, the amounts of mineral admixtures (e.g.…”

“…fly ash (FA), ground granulated blast-furnace (GGBS), limestone powder (LP) and silica fume (SF)) are given directly, without any detailed explanations or theoretical support. Moreover, due to the complex cementitious system of UHPC (extremely low water amount and relatively high SP content), the influence of different mineral admixtures on the hydration kinetics and properties of UHPC still needs further clarification [6][7][8][11][12][13][14][15]. As commonly known, GGBS has hydraulic properties although the rate of the reaction with water is low [16].…”

“…The use of quartz sand or aggregates of volcanic origin, the elimination of large fractions of aggregates, the application of extremely low water/binder ratios, reducing the CaO/SiO factors by adding silica fume (or other mineral additives with high silica content), the addition of steel fibres and the use of hydrothermal processing in order to improve the microstructure all represent a generalised approach to designing a mixture of UHPC (Yang et al 2009). …”

Abstract. Ultra high performance fibre reinforced concrete (UHPFRC) is cementitious composite with very high strength, and when compared with ordinary concrete it is a more superior material both in terms of its mechanical properties and its durability. In order to predict the behaviour of UHPFRC beams, first of all, experiments were carried out to investigate the mechanical properties of composites containing 2% and 4% of steel fibres. Following this, four beams of 2 m in length were tested by subjecting to four point bending. Two beams contained only micro steel fibres, while the remaining two contained conventional steel bar reinforcement. On the basis of experimental studies and recommendations by the AFGC for UHPC, the behaviour of the beams was modelled and optimization was carried out using genetic algorithms (GA) according to the criterion of minimum price. In this paper, the prices of individual UHPFRC beams are also shown in comparison with beams, which contain steel bars or prestressed reinforcement.Keywords: ultra high performance fibre reinforced concrete, optimization, beams, genetic algorithms.

Ultra‐high‐performance fiber‐reinforced concrete (UHPFRC) is a relatively new construction material. In comparison with conventional high‐strength concrete, UHPFRC does not usually contain coarse aggregates larger than 6–7 mm in size. This paper presents the outcomes of an experimental study of UHPFRC beams subjected to four‐point loading. The effect of two parameters was studied, namely, the fiber content and the temperature of the curing water. Eight UHPFRC beams were tested, comprising six beams reinforced with rebars and two beams without rebars. Three fiber contents were investigated in this study (1, 2, and 4% in volume). The study investigated two curing temperatures of water, 20 and 90°C. The results presented in this paper include deflections, toughness energy, and moment capacity and also includes a comparison with calculations according to EC2 provisions. A minor difference was observed in the deformation and flexural behavior of beams with fiber contents of 1 and 2% (in volume). However, beams with 4% (in volume) fibers exhibited a higher flexural capacity. Only flexural failure was observed and no shear‐related failure was recorded. Beams with 1% (in volume) fibers for both curing regimes had the highest peak load toughness energy. Beams reinforced with rebars and cured at 20°C had a significantly higher bending resistance.
